16'Claims.

This invention relates to an instrument for applying tape and constitutes an improvement on the subject matter of Letters Patent 2,123,415 issued to Dimitri L. Gorbatenko on July 12, 1938.

The taping instrument forming the subject matter of the aforementioned patent consists of a resilient pressure roller for engaging a tape, a handle for guiding the roller and for pressing the tape against a surface, means for holding a supply roll of tape, and means for heating the tape as it is fed from the roll.

The present invention includes these elements in improved form and, in addition, provides means for cutting the tape when a desired length has been fed from the supply roll, thus obviating the necessity and inconvenience of using separate cutting means such as scissors or the like. It is an object of this invention to provide a fully self-contained eflicient taping instrument.

In general terms the objects of this invention are attained through the provision of 9. casing for a supply of tape, an arm integral therewith for guiding the tape, a pressure roller for applying the tape, means for severing the tape, and means for heating the tape as it is fed from the supply roll.

' While the invention forming the subject matter hereof has been designed particularly for use in the furriel"s art wherein tape is heated to soften an adhesive substance thereon and ap plied along the inside edges of the pieces of fur to be sewn together, it should be understood that the principles of the invention will find many other uses. For instance the heating means may be eliminated or simply disconnected for the application of cold process tape such as Scotch tape. Also the invention may take many additional forms without departing from the spirit thereof; hence, the form shown and described is to be deemed illustrative only.

In the drawing forming a part hereof Fig. 1 is a perspective of a preferred form of the taping instrument forming the subject matter hereof,

Fig. 2 is a longitudinal section instrument,

Fig. 3 is a side elevation of the to that shown in Fig. 1,

Fig. 4 is a bottom plan view of the device,

Fig. 5 is a perspective view of the cutting. means,

Fig. 6 is a sectional plan view taken along the line 6-6 of Fig. 2, and

Fig. 7.is a section along the line 1-1 of Fig. 1.

In the preferred form illustrated in the drawof the taping device opposite (c ne-e2) lng there is included a case III, adapted to contain a suitable supply roll of tape, and an applicator arm II projecting therefrom. While the arm I I is here shown as cast integral with a portion of the case I 0, it willv be appreciated that the same may be a separate piece attached in any conventional way. The case I is pro vided with a cup-like sector I2 having an integral stud I3 forming a journal for the core I 4 of a tape roll. A cover I is provided for the case and is secured thereto by threaded engagement with the screw l6 co-axially disposed in the stud IS.

The tape I1 is unrolled from a supply roll I8 and passage through a slot I! in the casing ID from whence it is drawn in a channel 20, formed by the top edge of the arm II and the corresponding edge-of a detachable cover 2| for the arm, the latter being attached in the conventional way such as by the screws illustrated in the drawing.

Inasmuch as heating of the tape is desired in certain taping operations, such as the furriers art, we provide a plate 23 in the bottom of the channel 20 over which the tape is drawn. The edges of the plate 23 are received by the opposed slots 24 in-the cover plate, 2| and the arm II and thereby held in the p sition shown (see Fig.

7). As willbe noted from Fig. 2 an electrical element 25 is disposed beneath the plate 23 as the heating means therefor, which electrical ele. ment is provided with suitable leads 26 and 21, the latter passing rearwardly through the arm and through the conventional aperture 28 for connection with the usual outlet.

At thetip of the arm I I we provide a guide roller 35 over which the tape is drawn, which roller has a shaft 36 Journaled in the arm II and the cover 2| therefor. A pressure roller 31, which serves to apply tape to the desired surface, is disposed on the bottom of the arm II, adjacent roller 35, being journaled in the lugs 38 dependent from a frame member 39 secured to the arm I I.

As'clearly indicated in Figs. 1 and 2 in aplying tape the device is tilted and roller 3'! presses the tape against the surface to which it is being applied. The value of the device thus far'described is materially enhanced by the provision of convenient means to sever the tape when the desired length has been applied.

The preferred form of cutting means consists in a blade 40, having a cutting edge II, slidably received in the frame member 39, there being four cars 42 on said frame bent upon it to define the guide means for reciprocation of the said blade (see Fig. 4). The movement of the knife 40 to and from the cutting position (Fig. 8) is accomplished by the pivotally connected links 5 43 and 44, the first of which is connected to the blade 40 by means of a pin 45 through the ears 48 on the blade 40 (see Figs. 1, 2 and 5), and the second of which is connected to the bottom of arm H by means of the dependent ears 8? and a 10 pin 48. A spring 50, the spiral of which is on the pin 48, normally urges the link dd away from the bottom of arm I i and through the heretofore described linkage throws the pivotally connected end of link 48 outwardly drawing blade 48 rearwardly in its guides 42 and out of the cutting position (see Figs. 1 and 2). This movement of the blade is limited by the provision of a stop, illustrated by the screw 54 in the bottom of arm H (see Figs. 2 and 4). From the foregoing description it will be seen I that the cutting of the tape is effected by downward pressure on the casing It, to the position illustrated in Fig. 3', whereupon link it is forced inwardly against the urge of the spring 50 and, through the link 43, blade 60 is thrust outwardly in its guiding means 42. Since the cutting of the tape will be effected in the majority of cases as the mechanism is moved over the surface being taped, a roller M is provided on the pin 52 connecting links 43: and id, the function of which is to facilitate movement of the instrument'over the tape already applied without in anyway disturbing it. In thecutting operation, the apparatus is rocked by the-operator to the position shown in Fig. 3, that is, with both rollers 31 and 5! in contact with the applied tape.

In order to facilitate the severance of the tape we provide means for interrupting the feed thereof from the supply roll 18, to the end that the 40 tape may be under tension as the knife 42 is moved, into its cutting position. A braking member 55 of resilient material such as a thin sheet of metal, having an aperture 58 therein to encircle the stud i3, is riveted as at 51 at one end to the wall of the cup-like portion-of the casing l2.- Its opposite end is riveted to a plug 58 projecting through an aperture in the side of the.

cup-like portion [2 of the casing. Looking at Fig. 6 it will be noted that when the plug 58 is 5 pressed inwardly the braking element frictionally engages the supply roll of tape l8 and stops the feed therefrom-through the slot l9. Thus the tape 11 will be under tension from the roll to that portion thereof already adhesively 5,5 secured to the surface being treated, and upon which the rollers 31 and are pressed, thereby facilitating the severance thereof by the knife 40.

A keeper 60, in juxtaposition to the roller 35,

consisting of a U-shaped wire retained between to the tip of the cover 21 and the corresponding section of the arm ll. serves to hold the severed end of the tape I! in position for immediate application at the start of further taping operations.

From the foregoing it will be appreciated that the principle of the present invention is susceptible' of many changes and modifications. For instance, the feed and cutting means may be used for taping operations wherein the heating 7 of the tape is neither desirable nor necessary. For such uses elimination of the heating plate 23, the element25 andthe leads 26 and 21, or disconnection of the same, will be sufficient.

Further modification may be made without departing from the spirit of this invention and for that reason we desire protection in accordance with the full scope of the appended claims.
